Martin,
Thanks for the crisp answer. Much appreciated. Good to hear that you provide something that is usable *now* ...
> We will also provide a GoodRelations Annotator (like the "foaf-a-matic" of GoodRelations) and a Validation Services that helps keeping up data quality.
Yes, please. The sooner, the better - esp. the validation stuff.
Another quick Q: I dunno, but skimming the user guide at [1] didn't suggest to me that there are already real-world datasets (such as Amazon, etc.) available that have been published using the GoodRelations ontology - can you correct me on that one? IMHO this would really make a great linked dataset (I'm CCing linked data mailing list therefore ...).
Keep up the great work Martin!
Cheers,
Michael

Subject: Re: GoodRelations - The Web Ontology for E-Commerce
Hi Michael:
Thanks! As for relating it to [1]: As for as I understand that work, it is mostly about describing what a product *is*. GoodRelations is about describing the offers of such products. So [1] is for me rather an extension of what eClassOWL is providing - a vocabulary for products, and for exchanging vocabularies of products. The main overlap I see is that GoodRelations also contains (and must contain) a small top-level ontology for product ontologies, which is like a very small subset of what you can do with STEP.
I am pretty sure that this part can be extended in a compatible way so that it will be aligned with [1], but this very much depends on the actual modeling of [1] in OWL or future versions of OWL.
The primary goal of GoodRelations is to do *now what can be done now* with the current version of OWL on current, popular infrastructure. It's about making Semantic-Web-based e-commerce a reality in 2008...
By the way, instructions on how to create own GoodRelations-compliant ontologies for products and services are at
http://www.heppnetz.de/projects/goodrelations/documentation/vocabulary-dev
So in short: I personally think both efforts should eventually converge. But, based on a couple of years of work on simpler problems than those in the scope of the incubator group, I think it will be at least a few years down the road until the ambitious goals of the incubator group can be turned into deployable results.
Note that GoodRelations and eClassOWL 5.1.4 in combination are readily available
1. in current W3C languages,
2. usable on current infrastructure (repositories + reasoners)
3. compliant with all known W3C best practices.
You can really start annotating offers TODAY. I am not joking...
We will also provide a GoodRelations Annotator (like the "foaf-a-matic" of GoodRelations) and a Validation Services that helps keeping up data quality.
Best
Martin

Martin,
Great work! We'll very likely soon be able use it in our UAd project. One question, though, I wanted to ask you already at ESWC08 but (seems both) didn't find the time to talk in greater detail: How is this work related to the W3C Product Modelling Incubator Group [1]?
Cheers,
Michael

Subject: ANN: GoodRelations - The Web Ontology for E-Commerce
Dear all:
We are proud to announce the official release of the GoodRelations
ontology, a comprehensive effort for making e-commerce on the Semantic
Web a reality.
GoodRelations is a lightweight yet sophisticated vocabulary for
describing the details of offers made on the Web. It empowers
manufacturers and shop operators to express the exact meaning of their
offers in a machine-readable way. This allows search engines to support
more precise search, and partners in the value chain to automate their
content integration tasks.

GoodRelations complements the eClassOWL ontology, which is the first
non-toy ontology for products and services. Since the initial
release of
eClassOWL at ESWC 2005, that ontology has gained remarkable attention.
The latest version 5.1.4 provides more than 30,000 product classes and
more than 5,000 attributes for describing product features.
The relationship between these two ontologies is straightforward:
- eClassOWL provides classes, attributes, and values for
describing what
a product or service is.
- GoodRelations provides everything needed for describing the
relationship between a business entity and a product or service, i.e.,
the actual offer and its details. That’s also the origin of the name –
it’s an ontology for the relations between goods and business entities.
While eClassOWL is the largest ontology for products and services, one
can use any other products or services ontology in combination with
GoodRelations. Only a few guidelines must be met.
For example, the Austrian ebSemantics initiative is close to release
several products and services ontologies for particular
domains (events,
tickets, accommodation, etc.) that will be GoodRelations-compliant.
The main features of GoodRelations are as follows:
- Based on currently available Semantic Web standards, tools, and
infrastructure (“ready to run as of today”)
- Minimal requirements on reasoner support – any RDF-S-style reasoner,
OWL DLP, DL, or ter-Horst reasoner will work
- Support for all common business functions, like sell, lease, dispose,
repair, etc.
- Suits both for explicit instances, product models, and
anonymous instances
- Supports different prices for different types of customers
or quantities
- Supports product bundles in combination with all kinds of units of
measurements (“2 kg butter plus 2 cell phones for € 99” would
be no problem)
- Supports price specifications both as single values or ranges
- Supports intervals and units of measurements for product features
- Compatible with eClassOWL and other ontologies
- Supports ISO 4217 currencies
- Supports defining eligible regions
- Supports common delivery and shipping methods
- Supports accepted payment methods
- Offerings can be constrained to certain eligible business entities
(e.g. resellers only)
- Supports warranty promises, i.e., the duration and scope
- Supports charges for certain payment or delivery options; the latter
also individually per region
- Compatible with international standards: ISO 3166, ISO 4217,
UN/CEFACT, eCl@ss, etc.
GoodRelations is the result of about five years of work in progress,
carried out at multiple institutions. The ontology is released under a
Creative Commons Attribution 3.0 license.
Any feedback is very much appreciated! Also, if you need support in
adopting GoodRelations to your applications or data, please contact us.
We are already working with several organizations on making
GoodRelations part of their technology.
Best wishes
Martin Hepp
